Abstract

En oppstilling (10) av transdusere (12) for et sodar-system og driften av oppstillingen (10) i et monostatisk sodar-system er beskrevet. Oppstillingen (10) er sammensatt av et antall individuelle lydtransdusere (12). Hver transduser (12) utsender lyd i atmosfæren og avføler utsendt lyd som er blitt reflektert av atmosfæren. Transduserne (12) har en hovedsakelig sirkulær tverrsnittsform. Transduserne (12) er anordnet i et hovedsakelig plant, hovedsakelig heksagonalt gitterpakkings-arrangement.An array (10) of transducers (12) for a soda system and the operation of array (10) in a monostatic soda system are described. The array (10) is composed of a plurality of individual audio transducers (12). Each transducer (12) emits sound into the atmosphere and senses transmitted sound that has been reflected by the atmosphere. The transducers (12) have a substantially circular cross-sectional shape. The transducers (12) are arranged in a substantially planar, substantially hexagonal lattice packing arrangement.
